This product comes from a mysterious company with almost no information on them, and has been withdrawn from some markets because it contains an undeclared drug that could cause some people severe harm. Sounds like a nightmare, right? Read on for more about this weird and potentially-dangerous supplement:

Maxidus Overview

Maxidus is a supplement that's aimed at men who want to increase their sex drive and have harder erections. It's also supposed to increase testosterone, although it doesn't look like it's meant as a workout supplement. It comes in pill form, and is available without a prescription.

This product stands out from other herbal sex drive pills in that it's based mostly on traditional Chinese medicine. Unfortunately, as you'll see, just because it's unique doesn't mean it works.

Maxidus Claims

This is a libido enhancer for men, plain and simple. It doesn't claim to make you jacked, it doesn't claim to make your penis bigger or to make you have more confidence as a man – it simply claims to increase your desire for sex and to make your erections harder. The first website for this product we saw, (which looks like a generic blog page from 2006) doesn't come with over-the-top claims or pictures of scantily-clad women embracing chiseled hunks, and it doesn't try and set the customer up for a fall by telling them they already have a problem (“you don't have enough testosterone!”) and then giving them the “answer” (“Buy our pill!”). Later, we found another “US” page that is more crazy and boastful and full or more colorful language overall.

In fact, this is one of the most low-key products we've seen of this type. Just some information about the product, the ingredients, and a way to buy it. Simple. But in many ways, their website is too simple.

First, there's not much information about the company, Bio-Gulf International Corporation. It doesn't have its own website, and there actually seems to be more than one business with this name, so it's a little hard to track down who they are. This is not a good sign. When it comes to nutritional supplements, you need proof that a company can be trusted with your health (and your money!) but as it stands, we have no idea who these people are.

Secondly, there are only four testimonials on their website – hardly a flood of happy customers, and they're in such small font that they're almost impossible the read unless you've got flawless vision.

They offer quick delivery (1-3 days, they promise), but it isn't clear what their return policy is. If they'd included a proper Terms and Conditions section to their website, this info might be more obvious, but right now it's a mystery. Much like the company.

One shocking thing we learned is that, according to the Australian Therapeutic Goods Administration, Maxidus contains sulfohydroxyhomosildenafil, a derivative of sildenafil, which is the active ingredient in Viagra. This means that, far from being just an “herbal” product, this actually contains a drug that could seriously injure people who have heart conditions, and is only supposed to be taken by people who've had a doctor prescribe it to them.

Maxidus Ingredients

Maxidus consists of herbal ingredients used in traditional Chinese medicine, an herb and plant-based alternative medicine tradition stretching back thousands of years (although that's not proof that it works, necessarily). Here's a list of the main ingredients:

Eurycoma Longifolia

Astralagus Membranaceous

Epimedium

Flos Carthami

Herba Cistanches

Mormodica Charantia

Eurycoma longifolia is another word for tongkat ali, a popular aphrodisiac from Southeast Asia. It's supposedly able to increase testosterone levels and improve sexual desire, which is why it's been prescribed to men and women with sexual dysfunction for centuries.

Astralagus is a natural herb that's used to improve the immune system – although this product claims that it's to improve your “qi,” or vital energy. Either way, we're not sure why it's in this product, except as a “bonus” ingredient.

Epimedium is the scientific name for the colorfully-named Horny Goat Weed. It's supposed to help with … well, we think you can tell from the name what it's supposed to do.

Flos Carthami is another Chinese ingredient (called Hong Hua) that the product claims circulates blood to the genitalia. We didn't find any papers saying it actually does that. What did we learn? Stay tuned for the next section.

Herba Cistanches is – you guessed it – an herb in Chinese medicine found in the deserts of Taklimakan desert. Maxidus claims it improves sexual function and treats erectile dysfunction. What does research say about it? We'll get into that.

The Science Behind Maxidus

Welp, this is where Maxidus loses us. We looked up the ingredients in this formula, and the results weren't pretty.

Astralagus doesn't even have anything to do with testosterone or sexual health, but it seems like they included it to help with overall health. Ok, we'll take that. Except the fact that there's “insufficient evidence” that it has any effect on most of the things it's supposed to do, except for possibly helping control blood sugar levels in people with diabetes (WebMD).

Flos Carthami is proudly listed as an ingredient that send blood to the penis for harder erections and a better sexual experience – except that there's no actual evidence of that. In fact, the clinical studies we found on flos carthami all looked like they had to do with its effect on enzyme activity, or other chemical reactions, in mice, rats, and pigs. Nothing to do with sexual arousal at all (National Institutes of Health, USNLM).

What about herba cistanche? We met the same disappointment there: no study listed had anything to do with libido, but it was found to have some benefit to the immune system in mice (Wikipedia, “Cistanche”).

Mormodica Charantia has seen some clinical benefits as a way to treat infections, and it's also been seen to have an effect on lowering blood sugar levels for people who are diabetic (Wikipedia, “Mormodica charantia”; WebMD). We saw no references in clinical sources to testosterone or testosterone production – whoever's saying that it increases your testosterone levels is either making it up, or has no proof to show for it.

If it turns out this product does contain sildenafil, then you could be in for a real shock. While sildenafil is an FDA-approved ingredient that's supposed to combat erectile dysfunction, they've lied and misled people by not listing it on the product information. Sildenafil can cause harm for people with high blood pressure, and has to be prescribed by a medical professional for a good reason.

Word on the Street about Maxidus

There are only a few testimonials on the Maxidus website, and there really aren't any third-party websites with customer reviews to look over. So that means we're relegated to looking at the cherry-picked “reviews” Maxidus chose to represent themselves with:

“I'm 52 and my libido has been suffering – not because I don't crave sex, but because my penis won't work like it used to. I started taking Maxidus, and everything changed! After I take it I've got huge erections that last for a long time!”

“My sex life is better than ever before. I used to have a low libido, but now I'm having sex all the time! I walked around with an erection for hours after taking it.”

“I've tried several different products, and Maxidus is definitely the one I like the most. It works!”

“I love this. My wife can't believe how good it works, either! And there are no side effects, which I love.”

Keep in mind, there are only four of them, and they were chosen by the company itself. Hardly an unbiased selection of reviews. And keep in mind also that this product was found to contain a derivative of the active ingredient in Viagra, so there's a reason these guys are getting erections (that won't go away, even after sex) and walking around with them for hours – they're taking under-the-table Viagra. Viagra doesn't increase testosterone, it doesn't help the body, it's a drug that makes your penis erect, plain and simple. These men clearly have been conned.

Is Maxidus Worth a Try?

Maxidus relies on claims that it's natural and only contains herbs, ones that can safely and calmly help the body fill with testosterone so that men can want sex more. Too bad it's based on a lie: it secretly contains Viagra. That's why it's been recalled by the Canadian health authorities, and why the Australian government issued a warning to everyone that it contains an undeclared ingredient that could be possibly dangerous to people who don't know it's there. So much for being based on ancient Chinese tradition.

Do what the authorities are saying and avoid this at all costs. If you have no been prescribed Viagra, you have no business taking a supplement containing the same active ingredient. There are other products out there that have only herbal and plant-based ingredients, as Maxidus originally promised, and whether they work or not, at least you'll know what you're getting.

Maxidus vs Viagra

Turns out there's actually not much difference between Maxidus and Viagra. They both (apparently) contain similar active ingredients: Viagra contains sildenafil, and Maxidus secretly contains sulfohydroxyhomosildenafil, which is a derivative that's very similar and can pose health risks. These could include chest pain, nausea, diarrhea, and hearing loss(!). Viagra doesn't claim to increase sexual desire, only blood flow to the penis. Maxidus, on the other hand, claims to do the same thing, but also to increase libido and testosterone levels. Maxidus is available without a prescription, while Viagra is a drug and must be prescribed by a doctor.

Maxidus vs Vigrx Plus

Both of these products promise to improve your sex life: stronger erections, a bigger sex drive, and more pleasure felt during sex, including bigger orgasms. Unlike Maxidus, Vigrx Plus bombards you with reams of supposed scientific trials that are supposed to back up their claims about if and how the product works, while Maxidus mostly expects you to take it on faith. They both contain herbal ingredients, and some of them are even the same, like epimedium. Vigrx Plus is sold on Amazon, not just through its own website, and so you're able to get a better idea of what customers are saying about it: turns out they don't like it. Maybe that's why Maxidus only sells it through their site – they can control the bad press better that way!

Maxidus vs Libidus

It's not exactly clear, but it seems like Maxidus and Libidus might actually be the same thing. The newer, more flashy website we found for Maxidus even says “Maxidus = Enhanced Libidus!” and goes on to say the pills are the exact same, only Maxidus contains an added ingredient called Ku Gua – that's the Mormodica Charantia mentioned in the ingredients. Since it doesn't look like Libidus is sold anymore, Maxidus may have taken its place, and is sold in its stead. Some parts of the Maxidus US website even mistakenly refer to “Libidus” sometimes, so they might have even used the same website and just cut-pasted the new name in.
